Calculators, decoders and dump readers for automotive ECU work. Every browser tool runs entirely on your machine — your dump is read with the browser's own file API and the tools make no network requests at all. Disconnect from the internet and they still work. Nothing is ever sent anywhere unless you explicitly choose to share a sample.
Read the immobiliser ISN (DME and EGS) plus the full and short VIN from a Bosch MG1/MD1 EEPROM or flash dump. Runs in your browser — nothing is uploaded.
Rebuild a lost ATE MK60EC1 ABS/ESP long coding from the VIN, ECU part number and the car's PR options. Runs in your browser — nothing is uploaded.
Compare an original file against a modified one and see exactly which regions changed.
Verify checksums on Bosch EDC17, MED17, MG1 and MD1 files before you flash them.
Read the ISN and gearbox data from ZF 8HP Gen1, Gen2 and Gen3 EGS dumps.
